The best AI SDR tools, judged on the prices I could actually read

You do not have a salesperson. The clients you have arrived through people who already trusted you, your pipeline is a set of conversations you did not schedule, and the quarter looks fine right up until the month it does not. That is the situation in which someone types "best ai sdr tools" into a search box, and it is a reasonable thing to type.

One disclosure before anything else, because you should not find it halfway down the page: Klientee is my product. It appears in the price list below, next to tools that compete with it.

What the words "AI SDR" actually mean

SDR is short for sales development representative. In a company large enough to divide the work, that is the person who finds potential customers and opens the first conversation, so that someone else can hold the real meeting. An AI SDR is software sold as a substitute for that role.

In practice the label covers two quite different products, and the distinction decides whether a price is reasonable.

The first group sends. You supply the list of people and usually the message. The software handles mailboxes, spacing between messages, replies, and the hundred small technical details that decide whether anything arrives at all. Instantly, Smartlead, Saleshandy, lemlist and Woodpecker live here, whatever the homepage says.

The second group decides. It chooses who to contact, and often writes what to say. Regie.ai, AiSDR, Artisan and 11x sell this. Explee sells the raw material for it: data, by the thousand records.

The difference matters for one reason. If you have no salesperson, a sending tool leaves the hardest part with you: the judgement about who is worth writing to, and what to say to them. Paying for a sending tool and then never really using it is a common ending, and it is not a failure of the software.

The prices I could read, on 29 September 2026

Here is how these figures were collected, because the method has a limit you should know about. A headless browser loaded each vendor's own pricing page, waited for it to render, scrolled, and read the visible text. Nothing here comes from a review site or a comparison blog. Everything was captured on 29 September 2026, and prices change.

Six vendors, plus mine, showed a figure I could read:

• Regie.ai: tiers at $0, $41, $49, $125 and $150. A free tier exists.
• AiSDR: "Start at $250/mo." Tiers seen at $250, $900 and $2,500, with a per-campaign managed service at plus $149 per campaign and a fully managed service at plus $2,500 a month. Other figures on the same page: from $349 a month, from $94 a month, and from $59 per user per month.
• Explee: credits rather than seats. "Get $30 to try it", items between $1 and $15, and repeated lines reading from $5 per 1,000 and from $10 per 1,000.
• Instantly: $47, $97 and $358 a month.
• Smartlead: $32, $59 and $78 a month, with add-ons priced separately at $59, $39 and $29.
• Saleshandy: on annual billing, $34 a month (billed $408 a year), $76 a month (billed $912 a year) and $149 a month (billed $1,788 a year). Monthly billing is higher: $41, $99 and $189.
• Klientee, mine: $149, $349 and $749 a month per site.

Four did not show me a price. On Artisan, 11x, lemlist and Woodpecker I could not read a public figure on their pricing page on 29 September 2026. One capture of Artisan's page returned an invitation to book a demo and no number, and two later attempts returned almost nothing. Woodpecker's page rendered, offered a demo request, and contained no figure in the text I could read.

I want to be exact about what that sentence means. It does not mean those companies keep their prices secret, and it does not mean their prices are high. It means my browser saw no number, on that date, on that page. Some pages block automated reading. Some put the figure behind a toggle or a slider. If you work at one of those companies and I have this wrong, write to me and I will correct the line.

If you want the same exercise applied to the sending half of this market, I published it separately: the best cold email software, judged on the prices I could actually read.

What the billing unit tells you before the demo does

Four different ways of charging appear in that list, and for a firm of three to twenty people they behave very differently.

Per user per month is predictable, and slightly absurd when nobody in the company sells. You are buying seats for a role you do not have.

Per credit, or per thousand records, is the one that moves. A line reading "from $5 per 1,000" only becomes a price once you know how many thousands you need in a month, and you cannot know that on the day you sign. That is not a trick. It is simply a number you cannot budget against yet.

Per campaign, like the plus $149 per campaign line on AiSDR's page, prices the thing you would actually be buying: a piece of work that someone performs. It is the clearest shape in the list, and also the one that grows fastest if the thing works and you keep going.

Per site, which is what I chose for Klientee, means one business, one price, no credits and no seats. I chose it because I did not want my conversations with customers to be about consumption.

None of these shapes is more virtuous than the others. But a pricing page you cannot turn into a single monthly number is a pricing page you should not sign from.

The part that none of this software can sell you

This is the thought worth the rest of your attention.

A referral does an enormous amount of invisible work on your behalf. Someone who already trusts you explains what you are worth, in their own words, to a person who resembles them, at the exact moment that person has the problem. Three things line up at once: credibility, fit, and timing.

Automated prospecting can imitate the first two, badly or well depending on the care taken. It cannot manufacture the third. Nothing you buy this month makes a stranger need you this month.

What it can do is remove the dependence on your calendar. Referrals arrive when they arrive, which is usually not in the weeks when you have capacity. A system that keeps writing while you are deep in delivery does not create demand. It keeps you in front of the small number of people for whom the timing happens to be right, without requiring you to become someone who enjoys this work. That is the entire benefit. It is smaller and more useful than the category's marketing suggests.

It is also why the first question is not which tool to buy. The first question is whether the message you would send is one you would be glad to receive. If that is unsettled, what separates a cold email from spam is a better use of twenty minutes than any comparison list, including this one.

Where I would not buy any of this, mine included

If your order book is full and word of mouth is bringing you the work you want, none of these tools is worth your attention this quarter. Buy nothing. Come back when the referrals thin out, and notice that you will see it coming about two months late, which is the real argument for having something running before you need it.

If your reputation inside a small professional community is your main asset, weigh the risk properly. One message that reads like bulk mail, sent to someone who knows your clients, costs more than any of these subscriptions. The test I use is simple: would I be comfortable if this exact message were read aloud in a room containing my customers.

If what you actually want is a human being who takes the meeting, none of the software above does that. AiSDR publishes a managed service on top of its plans, at the figures quoted earlier. That is a different purchase, and it should be compared against hiring, not against software.

And Klientee specifically is the wrong answer in three cases. If you want to write and approve every line yourself, a sending tool at $32 to $97 a month gives you more control for less money. If your buyers are consumers rather than businesses, this is not built for you. If what you want is a list of contacts to export, Explee's model fits that and mine does not.

The cheapest way to find out whether any of it applies to you

Before paying anyone, including me, there is one thing worth doing: check whether a machine reading your website can work out who pays you and why. That is the input to every tool in this article. If the answer is wrong, no amount of sending fixes it.

That is what Klientee shows for free, with no account: you type your website address, and you read back what it understood about your business, with each statement supported by an extract from your own pages. If it has understood you badly, you have learned something useful about your website at no cost, and you can close the tab.
